dc.description.abstract | The second- and fourth-order apparent orientational order parameters of the core part of the molecule kP2lapp
and kP4lapp, have been measured by polarized vibrational Raman spectroscopy for a homogeneously aligned
ferroelectric smectic liquid crystal with three dimethyl siloxane groups in the achiral terminal chain, which
shows de Vries?type phenomena, i.e., very large electroclinic effect in the smectic-A sSm-Ad phase and a
negligible layer contraction at the phase transition between the Sm-A and Sm-C* phases. The apparent orientational
order parameters of the rigid core part of the molecule are extremely small both with and without the
external electric field in Sm-A. These results provide evidence for the existence of the de Vries Sm-A phase,
where the local molecular director is tilted at a large angle. | en |
